Free crypto seemed reliable before and many people are getting huge rewards from participating in airdrops and bounties but now, that is uncertain. Why? They said it is free but must comply with a certain task which is really hard to accomplish and still wastes your time.
Now, if we think about making money, therefore, we also have to spend money to invest and stop relying on these free promotions as they only disappoint us. Think about that there is NO FREE now, nobody gives us money freely without doing something.
